Honestly judging from the captain marvel scene, and various pictures of her toes and feet, more often than not, not painted, I don't think she is as crazy or girly about foot care as other celebrities. I don't think she's crazy into the self pampering at all to be honest.
What im trying to say is, I don't really think her feet are that nice. Plus if you Google her feet, you can find a couple gross raunchy beat up pics of her feet all messed up. I just don't think foot care is that important to her.
She's pretty and her feet and toes have a nice shape, but she's not in my top 10. I wouldn't doubt if she weren't ticklish at all there either
